INDEX.

Application led September 2, 1921. Serial No. 497,875.V

This invention relates to indexes of the j so-called visible index type in which a series of overlapping cards or sheets are supported on a frameby hinge connections; and the invention consists more particularlyvin the novel and improved construction of the hinge connection and its associated parts hereinafter described and pointed out in the Y claims.

Fig. 4 is an enlarged cross section of a4 detail on line 4-4 of Fig. 3; and

Fig. 5 is a similar cross section showing a modification. v

The frame of the index may be of usual construction and as herein shown ismade of sheet metal and consists of a back 6 and infolded marginal fianges 7, which form channels to hold the ends of the rails to which the index cards or sheets are hinged.

In the form shown in Figs. 1 to 4 inclusive, the rails l8 consist of strips of bristol board or other suitable material having sufficient resiliency to be sprung into the frame as shown in Fig. 1.

Mounted on the rail 8 are one or more card or sheet supporting members 9 (a pair being shown in the drawings) which are preferably made of a piece of sheet metal bent to form a body part extending across the face of the rail with its ends 10 bent over to embrace the longitudinal edges of the rail, and its middle part bent forwardly to form a projecting loop 11 which constitutes a hinge member as hereinafter explained. These sheet-supporting members are mountedl to slide lengthwise of the rails so as to be readily adjustable Vto any desired position thereon. n

Each index card or sheet 12 is folded on itself, and a slot or aperture 13 is cut in the sheet along the line of its fold, one for each sheet-supporting member. The forextends through the aperture, and the card i or sheet is separably attached to the sheetsupporting members by a wire 14 inserted through the loops 11. The wire 14 constitutes both a fastener by whichthe sheet is locked to the supporting member, and a pintle, or second hinge member, by which the sheet is pivotallyattached to the supporting members and to the rail. The ends of the wire 14 may then be bent to prevent it from becoming accidentally displaced.

By having the supporting members 9 adjustable on the rails, the slots or apertures may be formed in the cards or sheets withing to insure a fit, and the supporting members may then be adjusted until they come opposite the apertures; the parts may then be readily assembled as shown. This makes it possible in attaching or replacing index cards or sheets for unskilled users to apply cards which they may already have on hand out requiring close measurement or positionto the frame, and to make the necessary apertures without too great attention to precision. Obviously the apertures 13 may be placed in any position along the fold 15 of the sheet, and the supporting membersv adjusted accordingly.

In the modification shown in Fig. 5 the rail 16 instead of being a solid strip of sheet material, is of hollow or tubular formation. It may be made of any suitable sheet material such as sheet Celluloid, with its longitudinal margins 17 bent forwardly and inwardly, leaving a slot between them. The supporting member comprises the body plate 18, which slides in the tubular rail, and the forwardly projecting loop or hinge member 19 which extends through the slot between the bent-over margins 17. rI`he card or sheet 12 is fastened and hinged as before by the pintle 14 which passes through the loop 19.

I claim:

1. An index including spaced parallel iguides, rails slidable in the guides, said rails eing supported by lateral engagement one with the other, supports slidably mounted on the several rails and having projecting loops, intermediately folded sheets having apertures receiving the loops and fastener members engaged in the projecting portions of the loops and the fold of the sheets to secure individual sheets to their respective rails. l

An index including` spaced parallel guides7 rails slidable in the guides, said rails being` supported by lat-eral engagement one with the other, supports slidably mounted on the several rails and having projecting loops, intermediately folded sheet-s having apertures receiving the loops, fastener members engaged in the projecting portions of `the loops and the vfold oi the sheets to secure individual seetstotheir respective rails7 lsaid fasteners comprising-rods extending transversely of the sheets and `having bent terminal portions securing the partsin'as senibled relation.

3. An index including spaced guides, rails having terminal portions slidably mounted in the guides, said rails bearing` support-s adjustably mounted thereon and having' projeetingloops, folded sheets having apertures receiving the loops, the Width of the sheets being substantially that of the space between the guides, 'fastener membersrengapging the loops and the inner face of the'told for securing the sheets to the supports whereby the sheets are held `for pivotal movement between the guides, the loops of the several rails being` spaced `from each other7 whereby the lower edge of each sheet depends below the edge of the sheet carried by the rail thereabove.
